METHOD OF MANUFACTURING RECEPTACLES.

To all whom it may concern: 7

Be it known that I, WILLIAM RIGHTER Commas, citizen of the UnitedStates, residing at Wharnclifi'e, Wimbledon Park, Surrey, England, haveinvented new and useful Improvements in Methods of ManufacturingReceptacles, of which the following is a specification.

This invention relates to boxes or other receptacles made fromcardboard, soft metal or other material capable of being spun orcompressed in dies and of retaining the shapes so imparted to it.

The invention being described and illustrated as being applied in theconstruction of a cardboard box of circular cross section, theapplication of the invention to metal or to receptacles of other shapeswill be obvious.

It has long since been proposed to turn bot-l1 cardboard and metal overboth inwardly and outwardly was to form a bead or edging, and also toform ledges or recesses with which a separate iece may be caused toengage or be welded on suitable pressure being applied.

According to the present invention it is proposed to secure a morepermanent and effective locking of the parts than hasheretofore beencustomary, the invention further contemplating certain other detailimprovements, such as securing an ease and elasticity of applying a lidto the box, securing the top or part commonly used for a label, andother details which .will be better understood on reference to theaccompanying drawings in which' Figure 1 represents the section of atube which is to form the body of the box or lid as the case may be.Fig. 2 shows the result of the first operation thereon. 'Fig. 3 the dishshaped piece intended to be used therewith. Fig.4 shows such piecewhenbeing inserted into the body portion. Fig. 5 a plan of Fig. 3. Fig. 6shows the position of the parts after the dish shaped piece has beenpartially forced into the body portion. 'Fig. 7 roughly shows theposition the different parts assume after the final compression, and howthe lid or dish shaped piece becomes locked with the body portion. Fig.8 a similar view when the dies are so formed as to produce an externalring or flange. Fig. 9 a somewhat similar view to Figs. 4 an 6, exceptthat the curve or roll of the body and of the dish shaped piece are car-Specification of Letters Patent. Patented June 20 1911.

RETSSUED ried somewhat farther inward. Fig. 10 a view of same whenfinally compressed and showing the locking of the parts together. Fig.11 a view with a. loose label on the bottom of the dish shaped piecewhich will carry same up and stretch and hold same in position when theparts are locked together. Fig. 12 a view of the body portion when madeof lap welded tubes Qiowing a part cut away in order that the rollinward may be on material of even thickness. Fig. 13 a section of acompleted box and lid.

In said drawings the tube or body is marked 1, and, as shown in Fig..12,if made of lap welded or glued cardboard a section on line 2. 2. may beremoved so as to present an even thickness of material to be turned overor rolled inward, as indicated at 2, F igs. 2 and 4, although if desireda more complete roll may be made, as indicated in Fig. 9. Into the tube1 is inserted the dish shaped piece 3, as indicated in Figs. 3, 4, 5, 9and 11, the two parts being then compressed in suitable dies until theyfirst assume the position shown in Fig. 6 or Fig. 9, and on furthercompression are caused to flow so as to approximately assume thepositions'indicated in Figs. 7 8 or 10, as the case may be, thuseffecting a substantial locking together of the two parts, which arethen adapted for use either as a box body or a lid.

It is sometimes diflicult to satisfactorily apply round. labels to thetops of round boxes but this may be easily accomplished in the presentcase by placing the label 7 -in the dished part 3 before forcing theparts 1 together, and in this case not only will the label be securelyand centrally held without the use of paste or glue, but it may also betightly stretched as the parts are forced together. i

In Fig. 13 I have shown a completed box of preferred form, wherein Iemploy an inner tube 6 inserted in one of the outer tubes 1 to formtherewith the body portion of the box, the upper corresponding outertube 1 forming the lid thereof. The meeting edges of said tubes 1, aswell as the upper edge of inner tube 6, are preferably rolled, as shownat 4, so as not only to stiffen the tubes, but also to present roundedand somewhat elastic fitting edges, and said tubes 1 may also carry tubesections 5.

For the purpose of securing the inner tube 6 of the box to the bodyportion 1. a

projecting ring or bead 9 is formed, Fig. 13, so that on forcing thetube down into the box body 1, the ring or head 9 is compelled to springpast the inner roll 4 in the box body under which it becomes firmlylocked thus securing the inner part 6 to the outerpart 1, without theuse of an adhesive or other attaching means. Having now particularlydescribed and ,ascertained the nature of my said invention and in Whatmanner the same is to be performed, I declare that what I claim is 1.The method of fixing ends or bottoms to receptacles, which consists infirst formso as to become molded together into a locking joint.

2. The method of fixing ends or bottoms to receptacles, which consistsin first forming a roll-over part upon the tubular portion of thearticle, next fitting to it internally an end having a turn-up flangeadapted to enter and engage said roll-over part of the tubular body,which acts as a forming die for such end, and finally applying pressureto the combined parts so as to cause the roll and the flange to turnover and flow so as to become molded together into a locking jointprovided with flanges adapted to strengthen the receptacle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
